Balancing Chemical Equations begins with the first step of writing an equation - writing chemical symbols and formulas.

Of course before you can write an equation you must first determine what products are produced in the reaction. Students are referred back to chemical reaction types.

One of the biggest problems with writing balanced chemical equations is remembering the diatomic elements.

To balance an equation, students drag coefficients to the correct spot in the equation. If incorrect the coefficient flies back to the presenter's hand.

Several practice problems are given before the actual test on balancing chemical equations.

The test consists of 20 problems in which one student competes against another. Coefficients are dragged to the desired position and the balanced equation is then checked.
